Abstract (en)
A method and a video management system is disclosed. The method may include receiving a video stream from a camera and displaying the video stream on a display. The method may include obtaining, via an eye tracking sensor, gaze information for an operator watching the display. The method may include generating a historical gaze heat map for the video stream for a time period based on the obtained gaze information and determining a low interest area for the video stream based on the generated historical gaze heat map. The method may include instructing the camera to decrease a bit rate of the video stream in the low interest area.
